摘要
采用响应面优化方法,在单因素试验的基础上,用Design-Expert软件Box-Behnken Design建立数学模型,并对各因素及其相互间的交互作用进行分析.结果表明:回归得到的二次多项式模型极显著,模型的预测值与试验真实值之间的相关性达98.83%.优化后的最佳工艺参数:液料比60 mL·g-1,提取时间30 min,粒径大小40-50目.在该条件下香樟木质部提取物得率为4.65%,与理论预测值基本一致.
The mathematical model was established using Box-Behnken Design of Design-Expert software and effect of various factors and their interactions were analyzed as we ll.The results showed that the second order polynomial was the best model,the correlation between model prediction and test real value was 98.83%.The optimum extraction condition was as follows：liquid-solid ratio of 60 mL · g-1,extraction time of 30 min,particle size of 40-50 mesh.Under above optimum condition,the extraction yield was 4.65%,which was basically equal to theoretical prediction value.
